Name of the Vulnerable Software and Affected Versions: Lin-CMS-Flask version 0.1.1

Description: The issue allows remote attackers to execute arbitrary code by entering scripts in the Username parameter of the component 'app/api/cms/user.py'. This enables attackers to perform Cross Site Scripting (XSS) attacks.

Recommendations: For Lin-CMS-Flask version 0.1.1, as a temporary workaround, consider restricting the input for the Username parameter in the 'app/api/cms/user.py' component to prevent the execution of arbitrary code. At the moment, there is no information about a newer version that contains a fix for this issue.
